System for allowing below-ground and rail-to-rail input voltages

A capacitively isolated input system that permits sensing of an input voltage with a below-ground value or a below-substrate voltage value. Multiple input signals are received, and each input signal is connected to cross-connected switching components. Switched output signals are capacitively connec...

Beschreibung
Zusammenfassung:	A capacitively isolated input system that permits sensing of an input voltage with a below-ground value or a below-substrate voltage value. Multiple input signals are received, and each input signal is connected to cross-connected switching components. Switched output signals are capacitively connected to additional switching components and to a sensing amplifier. This system allows the sensing amplifier to receive capacitively isolated input signals and to provide corresponding output signals at voltages no lower than ground voltage.
